Conferences ============================================== 1.1. A Multipolar Universe?, Thessaloniki, Greece --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=26725 Starting: 2023-09-04 to 2023-09-07 Location: Thessaloniki, Greece Additional Information: https://sites.google.com/view/multipolar-universe-workshop/home Contact: tsagas[AT]astro.auth.gr Scientific Topic and Scope: Over the last few years there have been repeated claims of dipolar anisotropies in a variety of cosmological observations. These include dipoles in the number counts of distant astrophysical objects, like quasars and radio galaxies for example, as well as dipoles in certain cosmological parameters, such as the Hubble and the deceleration parameter. In view of these reports, the emerging question is whether the associated observations reflect some underlying generic anisotropy of the universe we live in, whether they are relatively late-time additions, triggered by the ongoing process of structure formation in particular, or they are mere artefacts of our gross misinterpretation of the data. The workshop will review the above mentioned issues, both from the observational and from the theoretical viewpoint, it will consider possible explanations and will discuss their potential implications for the future of cosmological research. ​Confirmed Plenary and Keynote speakers: Pravabati Chingangbam (IIA, India); Chris Clarkson (QMUL, UK); Chethan Krishnan (IIS, India); Christian Marinoni (Aix-Marseille Univ.

DomoSchool 2023: Einstein Equation in the dark side of the Universe, Domodossola, Italy --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=26755 Starting: 2023-07-17 to 2023-07-21 Location: Domodossola, Italy Additional Information: https://www.arsunivco.eu/2023/02/domoschool-2023-einstein-equation-in-the-da... Contact: sergio.cacciatori[AT]uninsubria.it The Domoschool 2023 edition wants to focus on these issues: one of the most debated current topics in the scientific environment concerns the dynamics of galaxies. The problem concerns both the cosmological scales, given that the galaxies appear to move away from each other with increasing acceleration, and the galactic scales since the gases that form the surrounding halo appear to rotate around each galaxy at a much greater speed than predicted by the Newton theory of gravitation. In the first case, a standard interpretation is to attribute the relative acceleration between the galaxies to an expansion of the universe caused by the presence of an energy that exerts pressure on the whole universe causing its expansion. This energy is called dark energy. In the second case, however, the gas motion seems compatible with the fact that the mass present in the given region is much greater than that which can be observed directly. So we can imagine that in addition to the visible mass, there is also some non-visible matter distributed around each galaxy, which considerably increases the mass of the galaxies. This is called dark matter. To explain the movements of the observed universe we arrive at the conclusion that ordinary matter should constitute only 5% of all matter in the universe, while about 68% would be dark energy and 27% dark matter. While dark energy is compatible with the presence of a cosmological constant, hypothesized by Einstein over a century ago, the nature of dark matter is much more mysterious, so much so that an alternative school of thought proposes instead the absence of dark matter (never revealed in any experiment to date) in favor of new laws of universal gravitation at ultra-galactic scales (MOND theories). A third stream instead investigates the possibility that non-Newtonian effects of general relativity could help settle the issue by decreasing the amount of dark matter needed to explain galactic motions. The aim of the school is to introduce Ph.D. students, postdocs, and young researchers, both in mathematics and physics, to this topic. Courses will be conducted at Ph.D. level by world-leading experts. Moreover, students will have the opportunity to give 20 minutes talks presenting their research on themes related to the main topics of the courses. Informal discussions will be strongly encouraged, and specific time slots (short talks) will be reserved for this important part of the school. The school is mainly dedicated to PhD students, postdocs and young researchers, but interaction with and among professors will be also encouraged. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.6.

Conference of the foundations of spacetime physics, Varna, Bulgaria ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2023/05/18/conference-of-the-foundations... Additional Information: https://minkowskiinstitute.org/meetings/2023/ The Third Hermann Minkowski Meeting on the Foundations of Spacetime Physics will be held in the famous Black Sea resort "Albena" (near Varna, Bulgaria) from 11 to 14 September 2023: http://www.minkowskiinstitute.org/meetings/2023/ It will commemorate the 115th anniversary of Minkowski's 1908 world-view-changing lecture "Space and Time," which presented the novel ideas of the spacetime structure of the world and the four-dimensional physics of spacetime. In addition to technical papers on spacetime physics, papers on closely related topics, including on conceptual issues of spacetime physics, will be also welcome. If relevant abstracts are submitted, there will be a special session on how Hermann Minkowski, had he been alive in 1915, might have reformulated Einstein's general relativity: whether gravitational phenomena can be fully accounted for by the non-Euclidean geometry of spacetime without the need to assume that gravitation is a physical interaction; in 1921 Eddington mentioned this possibility explicitly - "gravitation as a separate agency becomes unnecessary" (A. S. Eddington, The Relativity of Time, Nature 106, 802-804, 17 February 1921). Contributed papers in the form of extended abstracts of up to two pages should be emailed to minkowski2023[AT]minkowskiinstitute.org by June 15, 2023. Submissions will be reviewed and notification of acceptance will be sent by June 30, 2023.

The Twenty-Sixth Release of the Einstein Toolkit ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=26767 Additional Information: http://einsteintoolkit.org/about/releases/ET_2023_05_announcement.html Release Announcement We are pleased to announce the twenty-sixth release (code name "Karl Schwarzschild") of the Einstein Toolkit, an open-source, community-developed software infrastructure for relativistic astrophysics. The major changes in this release include: * kuibit 1.4.0, which, in addition to bug fixes, improves support for working with horizon data, timer data, and higher rank objects (See release notes for more details). Two new arrangements and thorns have been added: * The FUKA reader for numerical relativity initial data * TwoPunctures_BBHSF for binary black hole with scalar fields initial data New capabilities for existing codes: * Baikal and BaikalVacuum have been updated to have READ/WRITE declarations for automated ghost zone synchronization. Several variable groups (such as RHS variables) are also no longer included in checkpoint/restart operations. * particle_tracerET can now output the particles' four-velocity (contravariant and covariant); added support for binary output format; removed limit on the number of tracer particles In addition, bug fixes accumulated since the previous release in November 2022 have been included. The Einstein Toolkit is a collection of software components and tools for simulating and analyzing general relativistic astrophysical systems that builds on numerous software efforts in the numerical relativity community including the spacetime evolution codes Baikal, lean_public, and McLachlan, analysis codes to compute horizon characteristics and gravitational waves, the Carpet AMR infrastructure, and the relativistic magneto-hydrodynamics codes GRHydro and IllinoisGRMHD. The Einstein Toolkit also contains a 1D self-force code. The Einstein Toolkit uses a distributed software model, and its different modules are developed, distributed, and supported either by the core team of Einstein Toolkit Maintainers or by individual groups. Where modules are provided by external groups, the Einstein Toolkit Maintainers provide quality control for modules for inclusion in the toolkit and help coordinate support. The Einstein Toolkit Maintainers currently involve staff and faculty from five different institutions and host weekly meetings that are open for anyone to join. Guiding principles for the design and implementation of the toolkit include: open, community-driven software development; well thought-out and stable interfaces; separation of physics software from computational science infrastructure; provision of complete working production code; training and education for a new generation of researchers. For more information about using or contributing to the Einstein Toolkit, or to join the Einstein Toolkit Consortium, please visit our web pages at http://einsteintoolkit.org, or contact the users mailing list users[AT]einsteintoolkit.org. The Einstein Toolkit is primarily supported by NSF 2004157/2004044/2004311/2004879/2003893 (Enabling fundamental research in the era of multi-messenger astrophysics).
